i got the cheapest package from walmart. 69 bucks came with the recharger, power unit, one brush.

i didnt need the extra brushes nor the travel case for the extra 10-20 bucks. each brush comes with a cover anyway...they are already for travel. the power pack supposely lasts 1-2 weeks without recharging.

i can share my sonic care with family members...they just need to buy the replacement brushes for 24 bucks for a set of 2 at walmart.

the internet deal isnt bad at all. 59.99 is the cheapest ive seen so far...and it probably will go cheaper as it gets more common.
